Abstract |
Intraspecific allometric calculations of the brain to body size relation revealed distinct differences between 127 (67; 60) ancestral wild cavies and 82 (37; 45) guinea pigs, their domesticated relatives. The dependency of both measures from one another remained the same in both animal groups but the brains of guinea pigs were by 14.22% smaller at any net body weight. Consistent with results in other species the domestication of Cavia aperea is also characterized by a decrease of brain size. Fresh tissue sizes of the five brain parts medulla oblongata, cerebellum, mesencephalon, diencephalon and telencephalon were determined for 6 cavies and 6 guinea pigs by the serial section method. Additionally the sizes of 16 endbrain structures and those of the optic tract, the lateral geniculate body and the cochlear nucleus were measured. Different decrease values resulted for all these structures concomitant with domestication as was calculated from the amount of total brain size decrease and average relative structure values in the wild as well as the domesticated brain. The size decrease of the entire telencephalon (-13.7%) was within the range of the mean overall reduction as similarly was the case for the total neocortex (-10.7%) whereas the total allocortex (-20.9%) clearly was more strongly affected. The size decrease of the olfactory bulb (-41.9%) was extreme and clearly higher than found for the secondary olfactory structures (around -11%). The primary nuclei of other sensory systems (vision, audition) were decreased to less extent (lateral geniculate: -18.1%; cochlear nucleus: -12.6%). Mass decreases of pure white matter parts were nearly twice as high in contrast to associated grey matter parts (neocortex white versus grey matter; tractus opticus versus lateral geniculate body). The relatively great decrease values found for the limbic structures hippocampus (-26.9%) and schizocortex (-25.9%) are especially notable since they are in good conformity with domestication effects in other mammalian species. The findings of this study are discussed with regard to results of similar investigations on wild and domesticated gerbils (Meriones unguiculatus), the encephalization of the wild form, the special and species-specific mode and duration of domestication and in connection with certain behavioral changes as resulted from comparative investigations in ethology, socio-biology, endocrinology and general physiology. |

Abstract |
In der vorliegenden Untersuchung werden in einem Praxisbetrieb die Verfahrenskosten eines
Faltschiebers erhoben. Aufgrund des reduzierten Arbeitszeitaufwandes ergibt sich durch den
Einsatz des Faltschiebers eine jährliche Kostenersparnis in Höhe von 78 € je Pferd. Durch die
Mechanisierung der Entmistung kann fast 30 % der Arbeitszeit in der Pensionspferdehaltung
eingespart werden. Beim Einsatz einer Entmistungstechnik spielt jedoch nicht nur die Ökonomie,
sondern darüber hinaus auch das Pferdeverhalten eine Rolle. Im selben Praxisbetrieb wird
nach Installation der Faltschieberanlage das Pferdeverhalten beim Erstkontakt mit dem Schieber
beobachtet. Dabei zeigt sich, dass die Pferde den direkten Kontakt mit der Entmistungstechnik
und somit kritische Situationen vermeiden.
[In the survey at hand, the procedural costs for a v-form scraper are gathered. In the process,
it is found that due to the reduced working time requirement the use of a v-form scraper
saves € 78/horse/year. The mechanization of manure removal can reduce working time in
horse keeping by almost 30 percent. However, using manure removal systems, the profitability
is not the only crucial criteria. The behaviour of the horses plays an essential role, too.
Moreover the horses’ behaviour when first encountering the manure scraper is observed. The
study reveals that the horses avoid contact with the scraper and thereby also shirk critical
situations.] |

Abstract |
Eine tiergerechte, physiologisch und anatomisch auf die Bedürfnisse der Pferde ausgerichtete
Raufutterversorgung sollte die Kaubedürfnisse und die Beschäftigungszeiten von Pferden
ausreichend berücksichtigen. Daher – und auch aufgrund des bestehenden Kostendrucks bei
Raufutter – steigt das Interesse an Raufutterraufen, durch die möglicherweise die Futteraufnahmezeiten
verlängert sowie Futterverluste minimiert werden können.
Die vorliegende Untersuchung vergleicht das Fressverhalten und die Körperhaltung von acht
Pferden beim Einsatz von drei unterschiedlichen Futterraufen mit der Bodenfütterung in Einzelboxenhaltung.
Die Ergebnisse dieser Studie lassen den Schluss zu, dass der Einsatz von
Raufutterraufen die Futteraufnahmezeiten verlängert und somit längere Beschäftigungszeiten
für die Futteraufnahme gewährleistet werden. Außerdem konnte festgestellt werden, dass die
Pferde das Raufutter bei einer der drei untersuchten Raufen überwiegend mit natürlicher Kopf-
Hals-Haltung aufnahmen.
[Regarding the species horse, an appropriate supply of roughage should take into account the
need to chew as well as the need for occupation. In this context, and due to the current cost
pressure for hay, the interest in roughage racks increases. It is assumed that roughage racks
could help to extend the feeding time and reduce food losses.
The present study places the emphasis on the observation of the feeding behaviour of eight
horses in single horse boxes. Three different roughage racks are compared to traditional feeding
on the floor. On the basis of the results it may be concluded that the use of roughage racks
extends the feeding time and thus ensures longer occupation. In one of the three roughage
racks investigated the horses mainly eat in a natural posture of their head and neck.] |

Abstract |
Verhaltensbeobachtungen erfolgten an 112 Pferden in Mehrraum-Außenlaufställen mit Auslauf und Bewegungsställen. Bei vermehrtem Platzangebot sinkt das agonistische Verhalten in Bewegungsställen außerhalb des Fressbereiches. Mit zunehmender Stallgröße (überdachte Fläche und Auslauf) steigt in beiden Haltungsverfahren das affiliative Verhalten während das agonistische Verhalten mit Verletzungsrisiko sinkt. Daher wird für beide Haltungsverfahren ein möglichst großzügiger Stall je Pferd empfohlen. Die beobachteten Erkrankungen der letzten zwölf Monate zeigen vermehrt Hautkrankheiten in den Mehrraum-Außenlaufställen mit Auslauf, wohingegen Hufgeschwüre in Bewegungsställen auftraten. Wird der Fütterungsaspekt in den Bewegungsställen betrachtet, so ist die Transponderfütterung in Kombination mit ad libitum Fütterung aufgrund des deutlich geringeren, agonistischen Verhaltens beim Fressen, der reinen Transponderfütterung vorzuziehen. Mehrraum-Außenlaufställe mit Auslauf haben den Vorteil der synchronen Nahrungsaufnahme.
[The behaviour of 112 horses was observed in open stables and open active stables. Horses show less agonistic behaviour outside of the feeding area in open active stables as the space for each horse is augmented. Also the affiliative behaviour increases as a function of more space per horse while agonistic behaviour with a risk for injury decreases. These results are independent from the husbandry system. Due to this fact a stable with a larger area per horse is recommended. Diseases of the last twelve month were recorded and show skin diseases in open stables and abscesses in the hooves in open active stables. To consider the feeding in open active stables it was found that horses which were fed with hay controlled by transponders showed more agonistic behaviour in contrast to horses being fed using transponders but with access to hay ad libitum. Thus transponder feeding in combination with ad libitum feeding is recommended. Open stables have the advantage of synchronized feeding.] |

Abstract |
Abstract Considering the ever-growing demand of various breeding organizations for an objective, inexpensive, reliable, and easily conducted assessment of the behavior of horses, the aim of our study was to implement a novel-object test and a startling test into any kind of breeding performance testing to assess horses' temperament. Additionally, the influence of testing areas (familiar or unfamiliar), riders, and horse factors such as levels of training, breed, and age were of interest. Furthermore, recommendations for the practical implementation concerning the parameters should be given. Therefore, 1,028 horses over a period of 3 years participated in a temperament test consisting of 5 different stimuli. The horses were either ridden (61.8 %) or led by hand (38.2 %) by an unfamiliar professional rider (N = 43) or a familiar rider (N = 20). Live behavioral observations were taken by a trained observer. Overall, horses' scores for reactivity in the present temperament test were distributed over the whole scale, with lower means and higher standard deviations (6.7 ± 2.2-7.6 ± 2.1) than corresponding scores from the conventional personality evaluation in performance tests (7.7 ± 0.8-8.2 ± 0.5; P < 0.01). High correlations (r = 0.3-0.9; P < 0.001) between the scores for reactivity and the other behavioral parameters (emotional expression, activity, time to calm down, rider's aids) show a large influence of these parameters in assessing the horses' temperament. Factors like breed type, sex, and age had significant influences (P < 0.001) on different scores of the temperament test. In most cases, the rider or handler had no influence on the different scores assessed during the temperament test. The training level and the testing modus never had a significant influence on different scores. Only the testing station or location had a small influence on the scores for the stimulus “bridge” in some horses. Based on the results, it could be concluded that an implementation of a temperament tests into performance testing is possible during various types of testing procedure. Especially the assessment of reactivity, emotional expression, interest in the stimulus and rider's aids during and after passing the stimulus, as well as the time to calm down are important parameters for analyzing the horses' personality. |

Abstract |
The ability of many domesticated animals to follow human pointing gestures to locate hidden food has led to scientific debate on the relative importance of domestication and individual experience on the origins and development of this capacity. To further explore this question, we examined the influence of different prior training histories/methods on the ability of horses (Equus ferus caballus) to follow a momentary distal point. Ten horses previously trained using one of two methods (Parelli™ natural horsemanship or traditional horse training) were tested using a standard object choice task. The results show that neither group of horses was initially able to follow the momentary distal point. However, after more experience with the point, horses previously trained using the Parelli natural horsemanship method learned to follow momentary distal points significantly faster than those previously trained with traditional methods. The poor initial performance of horses on distal pointing tasks, coupled with the finding that prior training history and experimental experience can lead to success on this task, fails to support the predictions of the domestication hypothesis and instead lends support to the two-stage hypothesis.

Abstract |
The influence of the social environment on lateralized behaviors has now been investigated across a wide variety of animal species. New evidence suggests that the social environment can modulate behavior. Currently, there is a paucity of data relating to how primates navigate their environmental space, and investigations that consider the naturalistic context of the individual are few and fragmented. Moreover, there are competing theories about whether only the right or rather both cerebral hemispheres are involved in the processing of social stimuli, especially in emotion processing. Here we provide the first report of lateralized social behaviors elicited by great apes. We employed a continuous focal animal sampling method to record the spontaneous interactions of a captive zoo-living colony of chimpanzees (Pan troglodytes) and a biological family group of peer-reared western lowland gorillas (Gorilla gorilla gorilla). We specifically focused on which side of the body (i.e., front, rear, left, right) the focal individual preferred to keep conspecifics. Utilizing a newly developed quantitative corpus-coding scheme, analysis revealed both chimpanzees and gorillas demonstrated a significant group-level preference for focal individuals to keep conspecifics positioned to the front of them compared with behind them. More interestingly, both groups also manifested a population-level bias to keep conspecifics on their left side compared with their right side. Our findings suggest a social processing dominance of the right hemisphere for context-specific social environments. Results are discussed in light of the evolutionary adaptive value of social stimulus as a triggering factor for the manifestation of group-level lateralized behaviors.
